A method of detecting a control channel includes receiving data transmitted via a control channel. A path metric and a correction term is computed based on the received data. A decision metric representing a sum or a difference of the path metric and the correction term is computed. Based on the decision metric, it is decided on a detection of the control channel.

A device such as a turbo decoding device is proposed in which an intermediate buffering device including an address buffering device and an element buffering device is communicatively coupled to a plurality of processing devices and a memory device. During a cycle of a parallel decoding process, the intermediate buffering device receives, from two different processing devices, first and second address information respectively corresponding to first and second elements of a code sequence stored in the memory device. During the cycle, the intermediate buffering device transmits a request for the first element to the memory device based on the first address information and stores the second address information in the address buffering device. Subsequently, during the cycle, the intermediate buffering device receives first element information corresponding to the first element from the memory device and stores the received first element information in the element buffering device.

An iterative decoder for decoding a code block comprises a computation unit configured to perform forward and backward recursions over a code block or a code sub-block in each decoding iteration. A first forward/backward decoding scheme is used in a first iteration and a second forward/backward decoding scheme is used in a second iteration. The first and second decoding schemes are different in view of forward and backward processing.

Iterative decoder

A device such as a worker, window-size and iteration control unit (WWICU) is proposed. The WWICU determines processing, iteration, and window information based on format information indicative of one or more formats to be processed by a decoding process. The processing information may include a number of parallel workers, the iteration information may include a number of half-iterations, and the window information may include a window size to be used in the decoding process. The WWICU then determines time information including a total cycle count based on the processing information, the iteration information, and the window information. In response to determining that the total cycle count is not beyond a threshold value, the WWICU may transmit configuration information including the processing, iteration, and window information to a device, such as a turbo decoding device, configurable to perform the decoding process based on the configuration information.

Worker and iteration control for parallel turbo decoder

When installing and maintaining a wireless sensor network in a medical or factory environment, distribution of keying material to sensor nodes () is performed by a key material box (KMB) (), such as a smartcard or the like. The KMB () has a random seed stored to it during manufacture, and upon activation performs an authentication protocol with a sensor node () to be updated or installed. The KMB () receives node identification information, which is used in conjunction with the random seed to generate keying material for the node (). The KMB () then encrypts the keying material for transmission to the node (), and transmits over a wired or wireless communication link in a secure manner. The node () sends an acknowledgement message back the KMB (), which then updates the nodes status in look-up tables stored in the KMB ().
